RX560 works in PCI-E x8 and not x16?

Today, I noticed in GPU-Z that the Bus Interface: PCIe 3.0 x8 @ x8 1.1

During the render test: PCIe 3.0 x8 @ x8 3.0

The card is inserted in PCIe x16

Charge ASUS PRIME B350M-A

Question: why the card works at x8 and not x16 what to do and where to go?

Thank you. Is. As I am in matters of iron wood from head to toe where I could read about why this happens?

No, not so.

That is, not all adapters necessary x16 mode? And what does it depend?

PS

While there are still people who ask questions like: "how to upgrade the PCIe 2 to PCIe 3 somewhere in the wind?" I'm not so ashamed to ask such questions. - Christian.Bauch commented on June 5th 19 at 21:24

Not all. For this particular video card x8 will be enough for the eyes. - Aurore_Jenki commented on June 5th 19 at 21:27

1 of pci-e videocapture doesn't need not that in 16 lines, even in 2. Ie any pci-e video card will work without problems even in pci-e x1 mode/nest. A greater number of lines is used to increase throughput. To have the bus bandwidth pci-e more than the bandwidth of VRAM - does not make sense.

where can I read about why this happens?

In the standards for pci-e. - chaz commented on June 5th 19 at 21:30

The clip has a built-in dimension of x16, but it involved only 8 lines PCI. So all you have the rules work. - elenora_Carroll commented on June 5th 19 at 21:33
, , , okay, thanks for explaining that. I've got a plan to change this miracle for a GTX 1060 and all of a sudden because of this sudden news has decided that I have a charge that is not okay. - Christian.Bauch commented on June 5th 19 at 21:36

Note the section of the Expansion Slots in the specifications for your motherboard. - Keanu32 commented on June 5th 19 at 21:39

I have Ryzen 5 1600 (it's, like, 1st Generation) https://en.wikipedia.org/wiki/Zen_(microarchitectu... - Christian.Bauch commented on June 5th 19 at 21:42

Well, well, it means there is no problem. - Keanu32 commented on June 5th 19 at 21:45

And what you have all of a sudden the CPU?
PCI-E x16 slot connected to the processor and this has a small disclaimer:
Ryzen AMD™ Processors
1 x PCIe 3.0/2.0 x16 (x16 mode)
7th Generation AMD A-series/Athlon™ Processors
1 x PCIe 3.0/2.0 x16 (x8 mode)

Depending on the CPU slot can be x8 only.
However bandwidth RX560 should be enough so.
